Abstract

 Aim of the Syudy: The existence of Kugels artery has been rarely reported in literatures. In this study, I have explained the existence and course of Kugels artery. This will be helpful for the cardiologists to analyse the role of Kugels artery in the pathogenesis of valvulitis and lesions of the commissures and the base of the Heart. Kugels anastomotic artery has been described as a constant circumflex branch usually from its anterior part traversing the interatrial septum to establish direct or indirect anastomosis with the right coronary artery. Its existence has been questioned. Materials and Methods: 32 Heart specimens were dissected. The origin course and termination of Kugels artery was traced. Results and Conclusion: Out of 32 hearts specimens dissected, Kugels artery was found in 8 hearts. The main supply to the atrioventricular node is from the posterior interventricular branch of right coronary artery. Various studies explain that Kugels artery is an accessory blood supply to the atrioventricular Node. Kugels artery is said to terminate near the crux. Here it acts as a source of collaterals with atrioventricular nodal artery.
